Facilitation of emotion regulation with a single dose of escitalopram: A randomized fMRI study

Abstract

Acute antidepressant administration modulates neural activity consistent with decreases in negative emotion processing bias. However, studies are yet to examine whether treatment facilitates neural activity during reappraisal, an adaptive emotion regulation strategy associated with behavioral treatment response. Here we examine the impact of acute administration on reappraisal of negative stimuli using pharmaco-fMRI. Thirty-six healthy female participants completed two sessions of fMRI scanning, separated by a one-week washout period. A single dose of the selective serotonin reuptake inhibitor, escitalopram (20 mg) was administered to participants using a double-blind, randomized, placebo-co..
